HEATING SHIlS Specification of Letters Patent.l

AND THE LIKE.

resented oct. 2o, i914.

@riginal application led November 1, 1913, Serial No. 788,769. Divided and this application led February 24, 1914. serial No. 820513.

To all whom it may concern Be it known that I, MALCOLM MAoLnon, a subject of the King of Great Britain, and resident of Toronto, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in the Heating of Ships and the like, of which the p following is the specification.

rlhis invention relates to the heating of ships and other types of maritime vessels, and the object of the invention is to prevent the formation of ice on the hull of a ship,

and it consists essentially of providing a heated zone located partially below the water' line of the said ship and extending upwardly and across the deck thereof, the parts being arranged and constructed in detail as hereinaftermore particularly described in the following specification and accompanying drawing forming part of the same.

In the drawings, Figure 1 is a perspective view of part' of the hull of a ship, the side and deck plates being partly broken away to show the ribs of the ship. Fig..2 is a sec-` in the several drawings.

Itfmay be stated that the particular manner in which the heat is applied to the ship is the same as that adapted toheat lock gates andthe like described in my application, Serial Number 7 98,769, filed November V l, 1913, from which the present application has been divided. f y

Referring to the drawings', A represents part of the' body of-a ship which is preferably constructed of an outerhull B and an inner casing C.l The' inner casing G is located partly below thevvater line and extends upwardly and across the deck, the said casing' being rigidly secured to the ribs of the ship and to the outer hull by rivets and the-like.

The Vribs l may be of any usual construct-ion such as angle members carrying web plates attached thereto. In the embodiment illustrated Z shaped sections are shown which can be utilized in ships of small capacity. y.

The space D provided between the outer hull B and the inner casing C is sub-divided into compartments 3 by means of the ribs l, such compartments running transversely' around the ship. Should it be found desirable the-compartment 3 can be further subdivided by longitudinal members, and arranged in groups in which the adjacent compartments communicate with each other through the conduits or orifices 4, such oritices extending through the top and the bottom of consecutive ribs, the said groups of compartments being separated by the solid rib 6 located therebetween.

7 represents inlet pipes communicating with the compartments 3 through the oriices 8, such pipes being designed to deliver steam, hotair, flue gases and the like. to the said compartments. These hot gases circulate through the several compartments 3, the ribs'of the ship located betweenk the coml partments acting as baiiie plates, the said gases being discharged through the outlet pipe 9 to a suitable receiver where they can be reheated, or from which they are finally discharged.

and steam or the like isv delivered into every alternate compartment, the outlet pipe 9 being connected to the compartment located between those with which the inlet pipe communicates. The object of this will be clearly seen as circulation in each compartment must take yplace before the gases are discharged therefrom. lN-Then steam is utilized yas the heating element, the water of condensation is returned to the hot well from which it is fed to the boiler.

sirable to weaken the ribs of the vessel by having orifices therethroughan alternate method of forming communication between the several compartments is sho-wn in Fig. 3 and Fig. 4 where a groove 10 is cut in the inner casing between any two adjacent compartments. l

.-jiltliough the compartments 3 are primarily meant to form a heating zone around the casing, they may also be utilized as flotation tanks and they flow of hot gases to and from the said compartments can be cut off by a suitable valve arrangement as found desirable.

As many changes could be made in the above construction and many apparently Widely different embodiments of my invention, within the scope of the claims, con- The inlet pipes 7 are of any suitable forniv In heating small vessels since it is not de? structed without Vdeparting from vthe spiritl or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sensex lVhat I claim as my invention is:

l. The combination with the outer hull of a ship, of an inner casing located partly be.- low the water line and extending upwardly and across the deck, means of subdividing the said casing into compartments, and means of supplying heat to the said compartments, as and for the purpose specied.

2. The combination with the outer hull of a ship, of an inner casing located partly below the water line and extending upwardly and across the deck, ribs located between the outer hull and inner casing and adapted to subdivide said casing into compartments, such ribs having orifices therethrough, and

e, means of supplying heat to the said compartments, as and for the purpose specified.

y 3. The combination With the outer hull of a ship, of an inner casing located partially below the water line and extending upwardly and across the deck, ribs located between the outer hull and the'inner casing and adapted to subdivide the said casing into compartthrough which the steam and the like is designed to be discharged, as and Tor the purpose specified.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
